1 Claim. (Cl. 4-187) This invention relates broadly to mouldingstructures and more particularly to sink mounting means for installing astandard flat flange type sink in an opening in a drainboard or cabinettop.

It is an object of this invention to provide improved mounting meansparticularly adapted for rigidly holding a standard flat flange typesink in an opening in a drainboard or cabinet top and at the same timeforming a water-tight seal between the sink flange and the edge of thedrainboard or cabinet top circumferentially enclosing th openingtherein.

Another object of this invention is to provide a flat flange type sinkmounting means which comprises relatively few and simple parts and whichmay be used for mounting the sink in a convenient and easy mannerwithout requiring the use of any special tools or other expensiveequipment.

Still another object of this invention is to provide a flat flange typesink mounting means which is adjustable so that the sink may beinstalled at th correct level at the top of the opening formed in adrainboard or cabinet top.

These and other objects of this invention will become apparent from thefollowing description which is illustrated by the accompanying drawingsin which: a v

Figure 1 is a top plan view of a sink installed in a drainboard rcabinet top opening;

Figure 2 is a vertical sectional view on the line 2-2 of Figure l; 1

Figure 3 is a fragmental bottom view of a portion of Figure 1; and

Figur 4 is an exploded partial perspective view of the flat flange typesink mounting means of this invention.

The mounting means of this invention for positioning a flat flange sinkin an opening in a drainboard or cabinet top comprises a substantiallyT-shaped member in cross section which is adapted to be positioned withits vertical leg between the outer circumferential edge of the flat sinkflange and the edge of the drainboard or cabinet opening, the horizontalmember of the T member being adapted for resting on the top of theflange edge and the drainboard or cabinet top edge of the opening, thevertical leg having a plurality of spaced slots, there being wedgeshapedmembers adapted to be received by these slots, and each of thesewedge-shaped members being provided with screw threaded means foradjustably positioning the sink within the opening.

With particular reference to the drawings, the

preferred form of flat flange type sink mounting means consists of aT-shaped member is in cross section having a horizontal cross member I Iand a vertically extending leg l2. This T-shaped member ill ispreferably made of metal such as chromium, stainless steel, brass, orother type metal usually used in trimming cabinet edges or in formingjoining lines between adjacent cabinets and sinksinstalled in openingsin cabinets or drainboards. Along the length of the vertical member E2of the T-shaped member In there is provided a plurality of horizontallyspaced aligned slots it. A wedge-shaped rectangular member It isprovided and is received by each of the slots is. At the end of thewedge-shaped member M opposite that end received by the slot l3 there isprovided an internally threaded opening l5 for receiving an externallyscrew threaded set screw or thumb screw I6.

Since the sizes of sinks have been standardized in the industry, aT-shaped member Ill in the form of a rectangle usually having roundedcorners is provided for each standard sink size such that the length ofthe rectangle and its width are slightly larger than the length andwidth of the standard sink about which the substantially rectangularT-shaped member I 0 is to be placed.

In order to install a fiat flange type sink such as it in an opening I8provided in a drainboard or cabinet top, the sink I1 is placed withinthe opening and supported substantially in position by means of blocksor a jack from the underside. The correct size Tshaped flange member I0is selected and then placed about the edge of the flat flange of thesink l1 so that the vertical leg I2 lies between the outercircumferential edge of the drainboard or cabinet top opening and theedge of th fiat flange of the sink. The horizontal member H has one edgelying on the top of the drainboard or cabinet top and the other edgelying on the top of the flat flange of the sink ii. A wedge-shapedmember 14 is then inserted in each of the openings l3 so that one endopposite that having the screw threaded means it lies underneath thebottom of the drainboard or cabinet top and the other end lies in aposition such that the end of the set screw or thumb screw it will bearagainst the bottom of the flat flange of the sink l1 upon adjustment.Thereafter, each of the thumb screws or set screws Hi is adjusted inorder to bring the top of the flat flange of sink I! in alignment withthe top of the drainboard and in order to place the T-shaped memberunder tension and thereby form a seal between the horizontal member Hand the edges 3 of each of the flat flanges of the sink l1 and the topedge of the drainboard or cabinet.

The use of a wedge-shaped member M in place of a non-wedge-shaped memberhas particular advantage although either may be used in this invention.Not only does the wedge shape prevent the insertion of the member I4beyond a fixed limit such that each end of member I4 lies in its correctposition but also the use of a wedge-shaped member simplifies theassembly of the sink within the top of the drainboard. When thewedge-shaped members M are positioned in the slots 13 of the T-shapedmember It), the sink assembly is in a permanent position and thus allthat is necessary to hold the sink in place in this permanent positionis the insertion of the adjusting screws 16 in the internally threadedopenings l5 until they bear against the flat flange oi the sink II.

From the foregoing description it is seen that that the flat flange sinkmounting means of this invention provides a strong and durable structurewhich readily permits the easy installation of a sink in a cabinet topopening or drainboard opening. Furthermore, the resulting installationis one of extremely neat appearance which provides the necessarywater-tight seal between the sink and the cabinet in whose opening thesame is installed. Also, such an installation permits easy removal ofthe sink for the purpose of replacement if desired.

The foregoing description of the invention including the drawings is forthe purpose of illus- 4 tration and is not limiting as to the scope ofthis invention which is set forth in the following claim.

I claim:

In a cabinet top having a flat flange sink mountable in an openingtherein, mounting means for positioning said sink in said opening whichcomprises a substantially T-shaped member in cross section which isadapted to be positioned with its vertical leg between the outer edge ofsaid sink flange and the edge of said cabinet opening, the horizontalmember of said T adapted for resting on the top of said flange edge andsaid cabinet opening edge, said vertical leg having a plurality ofhorizontally spaced aligned slots, rectangular wedge shaped membersadapted to be received by said slots, one end of said wedge-shapedmember being in engagement with the underside of said cabinet adjacentsaid opening, the other end of said wedge-shaped member extending undersaid flat flange, the latter said end of said wedge-shaped member beingprovided with adjustable screw means for engagement with the undersideof said flat flange.
